During your warm up start with, chipping, pitching, some bunker play, move into your mid irons, 7 iron, 5 iron, and then into your 5 wood, hybrids, driver.  After you have finished with your driver move back to your wedges to create a lightness and softness in your arms then move to the putting green.  Start with short and long putting to a tee rather than a hole.  Do some speed drills and then finish off on the green knocking in 5-7 putts from 2 foot to feel confident with how you are rolling the ball.

It is not about the swing now; you have warmed up, trust yourself and enjoy the doing.
